Application filed January 26, 1917. SerialNo. 144,709. l

" To all whom it may concern .Be it knownthat IYKATBZERINA LIWAGZ,

a subject of the Emperor of Austria, residing at Philadelphia, in the county of Philadelphia and State ;of Pennsylvania, have invented certain new and useful Improve-- One important object of the ilivention'is to provide an improved general construction for ash sifters of this character. 7 ,7

A second important object of the invention is to provide an improved construction of ash sifter arranged to be directly connected with theash pit of a stoveorrange.

A third important object of the Invention is to provide an ash sifter of this descr1p-' tion with check or bafile means to prevent the passageof 'the;dust from the ashesupward to the stove where they would beapt to find their way outside and create dust in the kitchen or other room in which: the stove is located. A fourth important object of the invention is to provide an improved arrangement for disposing of the cinders after the cinders and ashes have been separated.

With the above and other objects in View, as will be hereinafter apparent the invention consists-in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing, and speclfically claimed.

In the accompanying drawing, like char- 7 acters of reference indicate like parts in the several views, and v Figure 1 is a side elevation partly in section and showing the improved ash sifter connected to the ash pit of a stove .or other like-device. i

,In-the drawings illustrating one preferred embodiment of the invention there has been shown the floor F of a building whereon is disclosed a portion of a stove S having an ash pit 10. Leading downward from the ash pit 10 is an inverted frusto-conical hopper 11 having at its lower end a flexible and rotatable joint diagrammatically indicated at 12. Connected to this joint is a pipe or chute 13 having an elbow ld at its lower end which is connected to the top 15 of casing 16. Mounted-on standards 17 is a hopper 18 the lower end of which 'is of inverted frustoconical form. The lower end of this hopper is furthermore closed by a hinged door 19 secured by a suitable latch 20 in its closed position. The casing 16 is surrounded at its upper end with aring 21 carrying resilient arms 22 the lower ends of which engage,

when the device is assembled, in notches 23 formed on the standards 17 so that by this means the casing and standards areheld in proper correlated position. At 2 1 is an oscillatory shaker member provided with a foraminous floor 25 and this shaker member closely surrounds thelower end of the casing 16 within the hopper 18. Furthermore, theupperedge of the hopper 18" is flanged as at 26 and in like manner "the upper end of the member 24 is provided'with a flange/27 which rests on the flange 26 so that the shaker member can be rotated with res ect-to the casing 16 and hopper 18.

provided in the wall of the. hopper 18 a slot 28 wherethrough passes an arm 29 provided on its outer end with a handle '30, the

' 11 order to effect this rotation there is V arm being connected to the shaker member 24. 1

Now, in the operation ofv the device, as thus far described theashes will pass-down from the ash pit through the small-hopper ll'and thechute I3=into the casing 16Qwhere they will be received on; the bottom hr the shaker member 2 1. Then, by oscillating the handle .30, the shaker ,membe'r will be oscillatedfand the fine, ashes will sift through the foraminous bottom 15 into the hopper 18 while the cind'ers willbe retainedin the r shaker member. After sulticient ashes have accumulated in the hopper 18 a suitable receptacle such as an ash can, wheelbarrow, or the like may be placed beneath the door 19 and the latter opened so that the ashes will drop into the receptacle which may then be carried away to any convenient place of deposit.

In order to dispose of the cinders which are in the shaker member this shaker memher is provided on its side with an opening which is normally kept closed by a sliding door 31 having a finger grip 32 at its upper end. At one point in the wall of the hopper 18 is formed an opening 33 from whence leads a chute 34 the bottom of which projects inward into the hopper to form a lip 35 whereon the bottom of the shaker member rests. The door 31 and opening 33 are so correlated with the slot 28 that when the arm 29 is at one extreme position in this slot the door 81 will be opposite the opening33 so that by pulling up on the finger grip 32 communication is established between the interior of the shaker member and the chute 34. In order to force the cinders out through the opening thus made there is provided a vertical shaft 36 which extends axially of the shaker member and carries 011 its lower end a curved blade 37 wider at its outer end than at the part adjacent the shaft 36 and the outer end of this blade is located closely adjacent the side wall of the shaker member 24. On the upper end of this blade is a crank handle 38 by means of which it may berotated and it will be seen thatwhen the blade is rotated in the direction of the arrow in Fig. 3 the cinders on the bottom or floor of the shaker member will be pushed outward toward the periphery of this member and carriedaround until they are pushed out of the door openingso that they may fall downward through the chute 3e and be received in a suitable bin or other receptacle for use in the stove.

This operationof shaking and separating the ashes from the cinders is of. course at: tended with a very considerable amount of dust which would ordinarily rise through the pipe or chute 13 but this is prevented in the following mannen In the upper end of this pipe 13 there is fitted an inverted frusto-conical nozzle 39 which is axially arranged in the pipe 13 and below this nozzle 39 is arranged a hollow cone spreader 40 supported by a spider 41. Now the mixed ashes and icinders will. passdownward through the nozzle 39 and be spread by the spreader 5L0 but when the dust tends to pass upward part of the'dustwill pass into the hollow conical spreader 4:0 and be there checked and dropped back while the remainder of the dust will tend to follow the arrow heads in Fig. 6 and be checked by the wall of the nozzle 39 so that practically all of the dust will be prevented from passing upward into the ash pit and thus finding its Way out into the room.

In order to support the shaft. 86 the top 15 is provided with a small bearing spider 42.

In the continuation of the operation of the device, after the cinders and ashes have been separated, the handle 30 pushed as far to the right as possible which will bring the door 31 opposite the'opening Then by opening the door and rotating the shaft 36 the cinders are pushed out and fall down the chute. There has thus been provided a simple and eflicient device of the kind described and for the purpose specified.

It is obvious that many minor changes may be made in the form and construction of the invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described but it is wished to include all such as properly come within the scope claimed, 7

Having thus described the invention, what is claimed as new, is

1. In an ash sitter of the class described, a hopper, an oscillatory shaker member supported within the hopper and having a toraminous bottom, a closure casing removably carried by the hopper structure and telescoping wit-hin the shaker member, means suspended from. the closure casing to rotate independently of the shaker member to throw'the cinders to the side of the shaker, an outlet through the walls of the hopper andshake'r to lead the cinders away and a closure in the bottom of said hopper.

2. In an ash sift-er, a hopper having a flanged seat formed around its top edge, an oscillatory shaker having an outturned flange upon its upper edge and rested on said flanged seat, so that the shaker is supported within the hopper solely from said seat, said shaker furthermore having a sitter bottom, a closure casing removably carried by the hopper structure and telescoping within the shaker member, means suspended from the closure casing to rotate independently of the shaker member to throw the cinders to the side of the shaker, and an outlet through the' walls of the hopper and shaker to lead the cindersaway.

3. In an ash sitter, a hopper having a flanged seat-formed around its top edge, an oscillatory shaker having its upper edge outwardly flanged and rested on said flanged seat,sothat the shaker is supported within the hopper solely from said seat, a closure casing carried by the hopper structure and telescoping within the shaker member, a
